“Franklin Electric’s SubDrive product line offers remarkable flexibility. Much of this flexibility comes from the internal switches inside the SubDrive/MonoDrive Connect family used by the installing contractor to select various options during installation. In the installation manual and elsewhere, these switches are referred to as ‘DIP switches’. For example, in SubDrive Connect, moving the DIP switch labeled SW1 to the ‘ON’ position enables WIFI operation. Position 5 of the SW1 selects between a pressure sensor (PS) or a

 pressure transducer (XDCR). Other DIP switches tell the unit which motor and pump are installed.

DIP switches aren’t unique to Franklin Electric and are used in many products. However, here’s the mystery… why on earth are they called DIP switches? Seems like an odd name for a switch or a row of switches. Unless you’re involved with electronics manufacturing, you would have no reason to know that DIP is an electronics acronym for Dual Inline Package. A 'DIP' is simply a rectangular component with two (dual) parallel (inline) rows of pins that mount through a circuit board. If that package has incorporated switches, then they are DIP switches.

There are a slew of other acronyms like this used in electronics manufacturing. For example, another type of circuit package is called a quad flat package, otherwise known as a QFP.

In the case of Dual Inline Package switches, over the years, the term DIP switch has taken on a life of its own, with most of us initially having no idea what the term actually means. Of course, you certainly don’t need to know where the term comes from to set a DIP switch, but now you know the origin of that funny name.”

Up To Speed: One Small Solution Will Prevent Many Future Headaches

“The best way to deliver groundwater is still with a submersible motor and pump. As you know, a submersible installation can be a tough environment. Even in the best of installations, things that are simply out of your controlPumptec Product Grouping can go wrong, such as: water levels can drop, electrical power can intermittently go bad, and pumps can become clogged. All of these things can quickly damage the unit downhole and lead to that frantic 'we’re out of water' call from the homeowner or farmer.

A Simple Solution for Your ‘Toolbox’

The above phone call doesn’t have to happen if you employ a slightly different, yet still cost-friendly approach. My tip for you: More times than not, the best investment you can make isn’t just in the product itself, but rather what you do to protect it. Your customer has invested a lot in you and their water system. A small additional investment in a Pumptec product will help ensure you won’t have to see that motor and pump for a very long time. They’re happy and you can focus on new installations.

Have You Met Pumptec Yet?

The Franklin Electric family of Pumptec, QD Pumptec, and Pumptec-Plus make protecting a submersible installation easy. It’s been proven in our industry for years, but I’m still surprised at how underutilized it is, costing thousands of dollars in damaged motors and pumps and headaches for contractors. To begin with, the entire Pumptec family protects against a dry well condition. Since submersible pumps are water lubricated and submersible motors are water cooled, any out-of-water condition in the well can make things even worse by damaging both. Pumptec products continually monitor the load on the motor and detect if it has become 'underloaded' or is not working as hard as expected. If that occurs, within three seconds, Pumptec will shut the system off and wait for the well to recharge (you get to choose how long).

Other conditions such as a flow restriction, a deadhead condition, or even a gas-locked pump will also cause a motor underload. The Pumptec family safeguards against these issues as well, saving the pump and motor from damage.

At the opposite end of the spectrum, a bound, tight, or clogged pump will create an overload condition on the motor. Once again, Pumptec protects the installation from any further damage by taking the motor offline within three seconds.

Underload and overload conditions are both mechanical issues, but what about electrical issues? Bad power can be a real problem, especially in rural areas. Voltage has no impact on the pump, but the motor must have the proper voltage. If it’s too high or too low, the motor will be damaged and eventually fail. Pumptec to the rescue. It continuously monitors the voltage going to the motor and if that voltage is off more than 10 percent either way, it removes power from the motor until the voltage returns to normal.

What is the Difference Between Them?

Pumptec and QD Pumptec look different, but the functionality of each is nearly identical. The only difference is in the packaging. Pumptec uses a QD Control Box enclosure and wires in minutes into either a 2- or 3-wire installation. QD Pumptec installs inside a QD Control Box in literally seconds. Pumptec-Plus adds capability up to 5 horsepower and has some added features, such as the rapid cycling detection that might occur with a water-logged pressure tank.

Underload, overload, undervoltage, and overvoltage can occur in any submersible installation. Franklin Electric’s Pumptec family protects against them all, making your job easier and less stressful for a very small additional investment.”

Up To Speed: Is it a Pressure Switch, a Sensor, or a Transducer?

01/18/2018

Up To Speed Graphic Thin VersionUp To Speed is a concise, technical blog compiled by industry veteran Mark Reeder. It provides an interesting fact, answers a thought-provoking question, or offers a cliffhanger from an actual site visit by one of our world-class Field Service Engineers.

“When options are added to any product, it’s important to eliminate the risk of a mix-up. One somewhat common and understandable point of confusion we hear is the difference between a pressure sensor and a pressure transducer.Pressure Switch

Before we clarify sensor versus transducer, let’s take a step back and first explain the pressure switch. We call it the on/off switch in a traditional water system. The pump/motor has two speeds, either on or off. A pressure tank stores the pressure and the pressure switch tells the motor when to start and when to stop. If we’ve installed a 30/50 psi pressure switch, it closes at 30 psi and starts the pump and motor. At 50 psi, the contacts in the pressure switch are forced open and the pump stops and waits for the next cycle.

In a variable speed system, the pressure is more precisely monitored and the pump speed adjusts to maintain a constant pressure. So, if the pressure is 48 psi and we programmed the system to maintain 50 psi, the pump speed increases a small amount. If the pressure reading is 52 psi, the pump speed decreases. This continuous adjustment in pump speed is what delivers constant pressure and matches demand.

This job of continually adjusting the speed of motor and pump falls to the variable frequency drive (VFD), sometimes just called the controller. Of course, for the controller to do its job, it must accurately know the system pressure. Franklin Electric has two different devices that accomplish this.

Clearing Up The Confusion: Sensor Vs. Transducer

1. Pressure Sensor – This is also known by some as a ‘Hobbs switch’. The key word here is sensor, as it Pressure Sensordifferentiates this device from the conventional pressure switch noted above. Similar pressure sensors are used in a multitude of other products as well, most notably in various engines to detect the presence of (or lack of) oil pressure.

In conjunction with a VFD, pressure sensors are similar to pressure switches in that they are either open or closed. However, unlike pressure switches, pressure sensors are very precise and good for millions of cycles. Around a given setpoint, say 50 psi, they are either open or closed. That is, 49 psi = closed; 51 psi = open. The controller continually adjusts the pump speed around this set point. Pressure sensors are remarkably simple and highly robust. Their only drawback: for more advanced installations, their capabilities are limited.

2. Pressure Transducer – It can be any device that measures and converts some physical parameter into an electrical signal. Hence, a pressure transducer converts pressure into an electrical signal. The key difference between a pressure transducer and a pressure sensor above is that the signal isn’t just on or off, it’s continuous. So, a 0 – 100 psi transducer can accurately tell the VFD the actual system pressure.

In the case of Franklin Electric’s SubDrive Connect, we give you both options. The product ships with a pressure transducer as ‘standard’, but the unit is still compatible with the pressure sensor (Hobbs switch). Please note: since the sensor and transducer function differently, they connect to a different set of terminals inside the SubDrive Connect.

Proper Connection

Here’s the punch line: The pressure transducer must be connected to the terminals labeled XDCR (short for Pressure TransmitterPressure Transducertransducer). The pressure sensor must be connected to the terminals labeled PS (pressure sensor). Connecting either one of the above to the wrong terminals will prevent the SubDrive Connect from operating.

One additional installation note: If you are using the pressure sensor, move the DIP switch to the PS position as well. This tells the SubDrive Connect where to look for the pressure measurement.

So, pressure switch, pressure sensor, or pressure transducer. Three devices that all have pressure in their names. Three devices that get the job done, but each in their own way.”
